Graph each equation using the slope and y-intercept.

4. y = 3 − 4 x - 3 5. y = 5 − 6 x + 1 6. y = x + 5

7. y = -

1 − 2 x - 4 8. y = x - 4 9. y = -6x + 3

10. A person weighing 150 pounds burns about 320 Calories per hour walking at a moderate pace. Suppose that the same person burns an average of 1500 Calories per day through basic activities. The total Calories y burned by that person can be represented by the equation y = 320x + 1500, where x represents the number of hours spent walking.

a. Graph the equation using the slope and b. State the slope and y-intercept of the graph y-intercept. of the equation and describe what they

represent. The y-intercept 1500 represents the number of Calories burned through basic activities. The slope 320 represents the number of Calories burned per hour when walking.
